Specification of Letters Patent.

Patented June 12, 1906.

Application filed August 25, 1905. Serial No. 275,797.

adapted for use on freight-cars, but capable for use in any place where a door or the like is to be locked by a fastening such as a hasp and staple.

This invention embodies a hasp and lock in Vone device, together with a pin which is passed through the staple on the door-post. Freight-car doors usually have a pin hung by a chain for fastening the hasp to the staple, and this pin is apt to become detached and lost and is also not conveniently sealed. In this invention the pin is carried in. the hasplock and cannot readily become lost or detached.

A further object of the invention is to provide a device with which any of the seals in common use may be used, such as a wire seal, a strap seal, ring seal, or padlock. The device will take the place of the common doorhasp and pin and provides means for effectively sealing a door.

In the accompanying drawings, Figure 1 is a plan view of the lock applied to a door. Fig. 2 is a plan view with the top or face plate removed. Fig. 3 is an edge view. Fig. 4 is an end view. Fig. 5 is a perspective view of the pin removed from the casing. Fig. 6 is a perspective view of a linger-piece which operates the locking-bolt.

Referring specifically to the drawings, the lock-Casing comprises a back plate 6 and a face or top plate 7, which has at its outer edge a flange 8, fitting around the edge of the bottom plate to exclude wet and dirt. These plates are fastened together by rivets at 9s. The back plate is recessed to form a space for the tumblers which operate the locking pin or bolt. Said bolt is indicated at 10 and slides within a tubular casing 11, formed by cored bosses on the plates of the casing. It is movable across a slot 12, through which the staple 13 on the door-post extends when the lock is fastened, so that the bolt will slide through the staple and lock the door. The casing is fastened to the door by a hasp-staple extending through a hole 14 in the end of the casing.

The bolt is operated by a swinging tumbler 15, which turns upon a stud 16 within the casing. The tongue 17 of the tumbler extends into the slot 18, formed in the lockingbolt, and when the tumbler is swung the bolt is raised or lowered accordingly to lock or unlock the door. The tumbler has a notch 18aL in its rear edge, which receives the end of an arm 19, pivoted to a stud 20 within the casing. This arm is operated by means of a finger-piece, which is most clearly shown in E ig. 6. This finger-piece comprises a ring 21, by which it may be taken hold of, from which project an upper branch 22 and a lower branch 23. The upper branch has a hole 24 to receive a wire seal, a slot 25 to receive a strap seal, and a hole 26 to receive the shackle of a padlock. The lower arm fits through an opening in the lower edge of the casing, which opening communicates with the recess containing the tumblers, and said arm has a notch 27, which engages over the arm 19, so that when the linger-piece is slid up or down the arm 19 is turned accordingly. The space between the upper and lower arms 22 and 23 is of proper Width to embrace or iit over the upper plate of the casing, so that the upper arm is on the outside of the casing and the lower arm is on the inside thereof, and the linger-piece will slide up and down, as indicated, to operate the bolt.

The lock may be sealed in various ways, as hereinbefore referred to. To this end a rib 28 is produced upon the face-plate standing beside the place Where the upper branch of the finger-piece slides. This rib has a wireseal hole 29, a strap-seal slot 30, and a hole 31 for a padlock-shackle arranged to register with the corresponding holes in the fingerpiece. The bolt 10 is also provided with a hole 32, arranged to register with a hole 33 in the tubular casing 11, and said casing in addition has a slot 34, which is located just above the upper end of the bolt when said bolt is in locked position. The slots and holes in the casing 11, the rib 28, and the branch 22 of the finger-piece are all in line, so that whatever seal is used may be extended through them all, so as to hold both the iinger-piece and the bolt. Thus with a wire seal, as indicated at 35, the seal is threaded through the holes in the bolt, the casing, the rib, and the finger-piece, and the parts are held against movement. When a strap seal, as indicated at 36, is used, it is threaded simi- IOO larly through the slot and eXtends across the casing 1l above the upper end ofthe bolt, so that the inger-pieoe oannot'be pullednorzthe bolt lifted. When a padlock is used, its shackle is put through appropriate holes-31 and 26 in the rib and inger-piece, so thatthe iinger-piece and tumbler, andconsequently the bolt, are held against movement. The lower end of the bolt l() is also provided with a hole 40, through which a keystone or ring-seal may be placed. y Means are thus provided whereby any ordinary kind of seal or lock may be used, and consequently the device will be capable of wide ap lication as a seal-lock. To open the lock, tliDe seal used has to be broken, after which the finger-piece can be lpulled down, which turns the tumbler and lifts the bolt from engagement with the staple.

It will be seen that this seal-lock in addition to its other advantages'carries its own bolt, which Ais held by the tumbler -so .that it cannot comeout. Consequently there vis no danger of its loss, and it is always `ready :for use. It is impossible to lift the pin or bolt without lthe downward movement of the iinger-piece.

The scope of the invention is not limited to the exact constructionshown, but is capable of various modifications, especially to adapt it for the use of barns and-.corn-cribs.

r-What I claim as new, and desire to secure by -Letters Patent, is-

El. A seal-lock comprising a hasp-casing having a slot Jfor a staple, a bolt slidable in :the casing and across the slot, a tumbler in the casing engaging the bolt and acting to slide the same, and a nger-pieceoperatively connected tothe tumbler7 and having means whereby it may be sealed against movement.

2. A seal-lock comprising. a casing having attaching means at one en and a slot at the other end, and adapted to actas a'hasp, a

vbolt slidable in the casing acrossthe slot, and

a fingerpiece separate from and operatively `connected with the bolt, said casing and finger-piece lhaving vregistering holes arranged to receive a seal.

3. A seal-lock comprising a 'hasp-casing having a slotto receive a staple, a bolt slidable in the casing across Athe slot, and a I"tinger-piece separate `from and operatively connected with the bolt; the casing,'fingerpiece and bolt having holes arranged to 4register .and to receive a seal.

In testimony whereof I have signed 'my name to this specification in vthejpresence of two subscribing witnesses.
